My department only equiped us with handheld stationary radars. When I first started I always wanted a mobile radar. I bought a used K55 system for $350. We are getting new decater radars and I will not need my old one. Its old, about the size of a DVD player. The antennas are the size of youth footballs. Its totally legal for the general public to have, no issues. Ill take $100 for it. If noone is interested ill probably mount the antenna behind my bumper, figure out some way to power it, and use it as a ghetto speed-o.....Think im bullshittin? We will see. Here is a picture. http://www.pbelectronics.com/mph_radar.htmIts k-55 K band
